Abstract: Side grooved CT-specimens and thick walled tubes with a circumferential crack on the outside were analysed with very detailed Finite Element calculations to determine the fracture mechanics parameters. Available are experiments for the creep crack growth of the CT specimens and for the fatigue crack growth of the thick walled tubes. The experiments were carried out by the Institute of Reactor Materials (IRW) of the KFA at temperatures above 700 °C. The results of the calculations can be summarized as follows : CT-specimens - The measured and the calculated creep deformations are well matched. Decisive is the knowledge of the exact parameters of the creep law. - The C* value is constant in the stationary creep domain and is well suited as a characteristic parameter for describing the creep crack. growth. Thick wall tubes - The K$_{1}$-values determined by the EPRI-handbook are conservativeMore exact finite element calculations give lower values.
